How to set up Proxy on Ubuntu?
I'm a Slackware guy, but I have a friend/professor who's looking to set up a proxy server on his Ubuntu machine for a network security class. Basically, he's clueless as to how to proceed, and I have to admit that the documentation out there for using Squid confuses even me. If anyone has any pointers for doing this, I'd appreciate them.
Also, an answer that's a little more in-depth than "use the point-and-click tools" would be appreciated. Thanks!
